- "Unraveling Multi-Valued Dependencies: A Key to Database Normalization"
Dive into the world of database normalization with our insightful video on Multi-Valued Dependencies (MVDs) and their impact on database design. Tailored for both budding and seasoned CSE professionals, this tutorial demystifies the concept of MVDs, explaining why they pose problems in relational databases and under what conditions they arise. Through a meticulously solved example, we illustrate the practical implications of MVDs and how they can lead to data anomalies and redundancy. Our guide not only clarifies the theoretical underpinnings but also equips you with the knowledge to identify and resolve MVDs, paving the way for more efficient and reliable database structures. Whether you're aiming to fine-tune your database designs or deepen your understanding of normalization principles, this video is your essential resource.

The way of explaination is incridible there is lots of lecture in CZcams but the way you teach is really simple and appreciable thanks a lot.
thank you, keep learning👍
excellent...now I understood the concept of mvd
keep learning 👍
Nice explanation ma’am
thank you 😊
💯💯
thank you ☺️
Thanks 🔥
keep learning 👍
Thankyou mam
Keep watching
Mam how to solve a relation R( A,B,C) consists A contains (a1,a1,a2,a2) B contains (b1,b1,b1,b1) C contains (c1,c2,c1,c3) how to list all the non trivial multivalued dependencies satisfied by the following relation
First you need to find all possible combinations of attributes to consider for functional dependencies. It can be between individual attributes or combinations of attributes.
attribute dependencies:
A -> A
A -> B
A -> C
B -> A
B -> B
B -> C
C -> A
C -> B
C -> C
AB -> A
AB -> B
AB -> C
AC -> A
AC -> B
AC -> C
BC -> A
BC -> B
BC -> C
ABC -> A
ABC -> B
ABC -> C
then determine if each dependency is trivial or non-trivial then find non-trivial multivalued dependencies satisfied by the relation R(A, B, C)
